If you have co-existent cataract and glaucoma then this could be the ideal option for you. Glaucoma is caused by obstruction/resistance to the drainage of the
clear fluid (aqueous) from inside the eye. As the eye in non-distensible (cannot stretch) any increase in the amount of fluid in the eye can send the pressure high and damage the optic nerve. The iStent is inserted at the time of cataract surgery and bypasses the area of resistance to fluid outflow. It aims to get the pressure down in the eye and hopefully allow us to reduce the number of (or even stop) your glaucoma eye drops.
This additional procedure extends the operation by only a few minutes and the benefits can be long lasting.
The iStent® is the smallest medical device that has ever been implanted in the human body
The iStent® is inserted through the clear, cornea cataract incision and can be performed under local or topical anesthesia.
Percentage of Patients Who Sustained IOP ≤21 mm Hg without Medication Use
Prospective, randomized, multicenter study across 27 US sites, of 240 patients with cataract and mild to moderate glaucoma were treated with ocular antihypertensive medications at baseline. All patients were assigned to a postmedication washout period before undergoing cataract surgery or iStent® implantation plus cataract surgery.
